<h4><a name = "tag_000_001_050">&nbsp;</a>NAME</h4><blockquote>
abort - generate an abnormal process abort
</blockquote><h4><a name = "tag_000_001_051">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="stdlib.h.html">stdlib.h</a>&gt;

void abort(void);
</code>
</pre>
</blockquote><h4><a name = "tag_000_001_052">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>abort()</i>
function causes abnormal process termination to occur, unless
the signal SIGABRT is being caught and the signal handler does
not return.
The abnormal termination processing includes at least the effect of
<i><a href="fclose.html">fclose()</a></i>
on all open streams,
and message catalogue descriptors,
and the default actions defined
for SIGABRT. The SIGABRT signal is sent to the calling process
as if by means of
<i><a href="raise.html">raise()</a></i>
with the argument SIGABRT.
<p>
The status made available to
<i><a href="wait.html">wait()</a></i>
or
<i><a href="waitpid.html">waitpid()</a></i>
by
<i>abort()</i>
will be that of a process terminated by the SIGABRT signal.  The
<i>abort()</i>
function will override blocking or ignoring the SIGABRT signal.
</blockquote><h4><a name = "tag_000_001_053">&nbsp;</a>RETURN VALUE</h4><blockquote>
The
<i>abort()</i>
function does not return.
</blockquote><h4><a name = "tag_000_001_054">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_000_001_055">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_001_056">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
Catching the signal is intended to provide the application writer with
a portable means to abort processing, free from possible interference
from any implementation-provided library functions.  If SIGABRT is neither
caught nor ignored, and the current directory is writable, a core dump may
be produced.
</blockquote><h4><a name = "tag_000_001_057">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_001_058">&nbsp;</a>SEE ALSO</h4><blockquote>

<i><a href="kill.html">kill()</a></i>,
<i><a href="raise.html">raise()</a></i>,
<i><a href="signal.html">signal()</a></i>,
</blockquote><h4>DERIVATION</h4><blockquote>
Derived from Issue 1 of the SVID.
